METAL WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 719,472, dated February3, 1903. Application filed May 20, 1902- Serial No. 108,205. (No model.)

To all whom it may concern:

Be it known that I, HUGH EDWARD KENNY, a citizen of the United States,residing at De troit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Metal Weather-Strips;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to an improvement in metal weather-strips; and itis embodied in the construction and arrangement described,

I5 and defined in the claims.

Many forms of weather-strips have heretofore been suggested,but theso-called metal strip is now very largely employed in preference toother types. In connection with metal strips it has been found that insecuring the strips to the frame of a window conveniently tacks or nailsare employed, which in some cases protrude and prevent an easy action ormovement of the sash. It has been suggested to obviate this by extendingthe base edges of the strip below the parting-beads, which necessarilyrequired the removal of the bead in the application of the strip.

Myinvention is designed to enable the ap- 0 plication of the stripdirectly to the base of the guidegroove of the frame or, if preferred,to the edge of the window-sash in a manner which will avoid thenecessity of the use of nails or tacks.

A further object of the invention is to provide a metal weather-stripwhich will have a base portion of sufiicient width to servesubstantially as a guide for the window-sash and a retainer for thestrip. 7

The invention relates more particularly to that type of metal stripwherein the sealingflange is formed by folding or doubling back thematerial, a type which has been eminently satisfactory and which resistsdistortion.

Intheaccompanyingdrawingslhaveshown several forms of strips embodyingthe principle of the invention; but it is to be understood that otherforms can be employed and changes made without departing from theinvention.

Figure 1 is a broken perspective view of a section of a window-casingwith a portion of the improved strip attached. Fig. 2 is a similar Viewshowing a strip of slightly-modified form. Fig. 3 is a cross-sectionthrough a sash-bar and the adjacent window-frame, and Fig. 4.- is across-section of a modified form of strip and its engaging parts.

In the drawings, A designates the windowframe; B, the parting-rails. Inthe frame between the parting-rails are formed two parallel grooves O,which are conveniently of equal depth.

D designates the window-sash, formed with an entering-groove d, locatedconveniently on a plane intermediate the grooves O.

E designates the metal strip, which is constructed, preferably, of zincand formed with the base portions 6 e of substantially uniform width, asshown in Figs. 1 and 3, their cen- 7o ter portions being bent outwardand looped or folded to constitute the sealing-flange E of the strip.The outer edges of the base portions are bent back at right angles, butparallel with each other,forrningsecuring-flanges 7 6 which are forcedtightly into the channels or grooves O of the window-frame. The baseportions constitute striking portions for forcing the anchoring-flangeinto the frame and also serve as guiding-surfaces, with which the sashcontacts in its up-and-down movemen t, thus atfordingasmoothcontact-surface antifriction in its nature.

The above-described construction is such that the strip is tightly heldin place, and the sealing-flange entering the groove (1 of the sashforms a very tight window and prevents all rattling.

In Fig. 2 I have shown a slightly-modified form, the base member orportion E being 011 go one side of the folded sealing-flange E Theanchoring flanges or edges 6 e are formed, respectively, by the edge ofthe outer returnbend of the sealing-flange and the outer edge of thebase member and may be constructed 5 of different widths, as shown, or aconstruction such as shown in Fig. 4 may be employed, wherein both ofthe anchoring-flanges are of the same width.

It is to be understood that while the pre- I00 ferred form ofconstruction is that illustrated in the drawings, wherein two separatedgrooves are employed with the parallel anchoring-fianges for the strip,the grooves may be located at any desired point between theparting-beads.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

1. A metallic weather-strip comprising a baseportion having twosubstantially parallel anchoring edges spaced apart and arranged at anangle to the base, and a sealingflange at an angle to the base,substantially as described.

2. A metallic Weather-strip comprising a base portion having twosubstantially parallel equal-width anchoring-flanges spaced apart andarranged at an angle to the base, and a sealing-flange at an angle tothe base, substantially as described.

3. A metallic weather-strip comprising a sealing-flange base portionsarranged at an angle to the sealing-flange, and parallel securing edgesat the outer edges of the base portions and arranged at an angle to thesaid base portions, substantially as described.

4. The combination with a window-frame having separated grooves formedtherein, a metallic weather-strip having its edges inserted in thegrooves and formed with a base portion at an angle to the said edges,and a return-bend portion extending outward at an angle to the said baseportion, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
